How to use the scientific calculator
Enter a mathematical expression and press Calculate or Enter. Examples include 2^10, sqrt(144), sin(30), log(1000), and (15/100)*850.
Degrees and radians
Trigonometric functions use degrees by default because that is common for everyday calculations. Switch to radians when working with calculus, programming, or mathematical formulas expressed in radians.
Calculation safety
This calculator evaluates only a controlled mathematical expression grammar. It does not execute arbitrary JavaScript code.
